Abstract. In this study, the trends and variability of annual precipitation totals rain days over land within Mediterranean region are analyzed. Long term ground-based observations concerning, on one hand, monthly (1900–2010) (1965–2010) from 40 meteorological stations were obtained Hellenic National Meteorological Service World Climate Data Monitoring Programme (WCDMP) Organization. On other high spatial resolution (0.5° × 0.5°) gridded data CRU TS 3.1 acquired Climatic Research Unit,...
Abstract The study presents a time-dependent analysis of threats from man-made climate change at 244 UNESCO cultural and natural heritage sites in the Mediterranean. hazards our research are estimated by indices based on extremes heat, fire weather conditions, heavy rainfall days, frost changes mean sea level aridity each site. These were calculated regional EUROCORDEX simulations, cover period 1971–2100 refer to two IPCC emission scenarios, namely RCP4.5 RCP8.5. A combined threat index was...
Abstract This study investigates the simulated changes in temperature and precipitation over Greece from nine Regional Climate Models (RCMs) for period 2071–2100 under A2 emission scenario evaluates their performance during control 1961–1990 using Greek gridded datasets of precipitation. In winter, most RCMs show a bias towards warmer dryer conditions higher inter‐annual variability lower than 1961–1990. summer, all cold maritime sub‐regions generally very small biases Concerning future...
This study investigates a range of precipitation interpolation techniques with the objective generating high-resolution gridded daily datasets for Greek region. The utilizes comprehensive station dataset, incorporating geographical variables derived from satellite-based elevation data and integrating ERA5 reanalysis. A total three different modeling approaches are developed. Firstly, we utilize General Additive Model in conjunction an Indicator Kriging model using only limited variables. In...
The Mediterranean region is particularly sensitive to climate change as it located at the crossroads of atmospheric processes. In Mediterranean, and in it’s eastern parts, rate warming more pronounced than global mean warming, with projected increase up to  2.5-3.0 °C simultaneous decrease precipitation 15 % by end century.Here, we investigate contribution different drivers regional trends, focusing summer season. We are analyzing surface temperature trends...
Abstract Current climate and future climate‐warming runs with the RegCM Regional Climate Model (RCM) at 50 11 km‐resolutions forced by ECHAM GCM are used to examine whether increased resolution of RCM introduces novel information in precipitation field when models run for mountainous region Hellenic peninsula. The model results inter‐compared output degraded match that GCM, it is found both present regional produce more than forcing GCM. At same time, increases warming even though they a...
Due to their rarity and intensity, Mediterranean Tropical-Like Cyclones (TLCs; also known as medicanes) have been a subject of study over the last decades lately interest has undoubtedly grown. The current investigates well-documented TLC event crossed south Sicily on November 7–8, 2014 added value higher spatial horizontal resolution through physics parameterization sensitivity analysis. For this purpose, Weather Research Forecasting model (version 3.9) is used dynamically downscale ECMWF...
We present the development of a physically-based dust source map for GOCART-AFWA module in WRF-Chem model. The new parameterization is based on MODIS-NDVI and an updated emission strength computed every 15 days from latest satellite observations. Modeling simulations period April–May 2017 over Mediterranean, north Africa, Middle East are compared with observations AOD at 31 AERONET stations. capable reproducing sources finer detail. overall performance model improved, especially stronger...
Abstract. This study analyses the variability and trends of ultraviolet-B (UV-B, wavelength 280–320 nm) radiation that can cause DNA damage. The caused by climate change due to enhanced greenhouse gas (GHG) concentrations. analysis is based on DNA-active irradiance, total ozone, cloud cover, surface albedo calculations with European Centre for Medium-Range Weather Forecasts – Hamburg (ECHAM)/Modular Earth Submodel System (MESSy) Atmospheric Chemistry (EMAC) chemistry–climate model (CCM)...
In the present study, spatial and temporal variability of Aridity Index (AI) in Mediterranean region during 30-year period 1971–2000 is analyzed. The analysis performed on a decadal timescale. Subsequently, projected change AI periods 2031–2060 (near future) 2071–2100 (far under RCP4.5 RCP8.5 emission scenarios comparison with (reference period) presented. input calculations are simulation results supplied by CORDEX EU project. total, an ensemble 20 combinations global climate models (GCMs)...
Forests provide a wide range of ecosystem services which are important for achieving sustainable development. Anthropogenic climate change has led to the increased frequency and severity forest fires, imply losses valuable services. This paper provides methodological framework based on Multiple Criteria Decision Aid methods determining relative regional vulnerabilities associated with fires. Different notions ex-post vulnerability defined area burned their relation regions’ certain...
Towards the investigation and further understanding of development propagation Medicanes, this study explores forecasting capability WRF model in case cyclone “Cleopatra” which affected with extreme rainfall strong winds Sardinia Calabria, Italy, November 2013.  This was unusual that it developed a warm core but did not fulfill its transformation into tropical-like because expand high enough tropospnere. The ERA5 reanalysis dataset dynamically downscaled from 31...
A broad spectrum of environmental processes such as radiation, cloud formation, ocean fertilization and human health are affected from the presence mineral dust. The transport dust particles is dictated by prevailing meteorological conditions well composition physiochemical properties themselves. Which, in turn, bound to soil mineralogy at source region.Numerical weather prediction models can estimate particles, yet a more refined mineralogical categorization significantly improve...
